JACOB HOTSAPILLAR, OF DAYTON, OHIO, ASSIGNOR TO THE COMPUTING SCALE.

SPECIFICATION forming part of Letters Patent No, 728,577, dated May 19, 1903.

Application filed April 14, 1892.

To all whom it may concern:

Be it known that I, JACOB HOTSAPILLAR, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Scales; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to improvements in weighing and price scales, or scales which will indicate the cost of goods at different rates per unit of weight; and the invention has for its object to materially simplify the mechanical features of the scale and to produce a scale in which while great accuracy is secured no diflicult or complicated manipulation will be necessary in the practical handling of the scale.

The invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a rear elevation, with the base broken away, of a scale embodying my present invention. Fig. 2 is a section on theline 2 2, Fig. 1. Fig. 2a is a section on the line art, Fig. 1. Fig. 3 is a section on the line 3 3, Fig. 1. Fig. 4 is a section on the line 4 4, Fig. l.

Like numerals refer to the same parts-in allthe drawings.

The base 3 of the scale illustrated inthe accompanying drawings constitutes a housing from which uprights 1 spring and carry at their upper ends a cap 2, these parts being of any preferred or usual construction in the class of platform-scales, although I do not wish to be limited to the use of the invention in this particular class of scales. Within the base-housing 3 and supported on corner-loops 18 and 28 are the platform or weight supporting levers 14 19 and 24 32, these levers beingv will be understood, may be of any usual and well-known construction, and, as is usual in Serial No.429,165. (No model.)

scales of this class, one of the levers is provided with a pivot or bearing, as at 22, for the attachment of the vertical connection extending up to the beam or parts above the base.

The framework above the base, formed in this instance by the standards and cap, is adapted to support the beams, two of which are employed, one for indicating value and the other a tare-beam or weighing-beam. In order to support the beams, the frame is provided with a tare or weighing beam yoke 7,

#having bearings for the reception of knifeedge pivots 5 of a tare or weighing beam 4 and with a value-beam stand 45, having bearings for the reception of knife-edge pivots 46 of a value-beam 4S.

The value beam is preferably made throughout a portion at least of its length with two bars, one above the other, as is common in this art, the upper bar 46 constituting the value-beam proper and the lower bar 49 the price-beam,-the two being rigidly connected and graduated the one to indicate total value and the other to indicate unit val- 'ues or rates per unit. The particular marking on the beams is not material in so far as the range 4of marking is concerned; but of course the markings or graduations on all the beams should in each scale bear a definite relation to each other, as is Well understood, in order to secure uniformity of action under all conditions.

-In order now to operatively connect the platform-levers or parts for receiving the goods'to be weighed with the beams,and at the same time avoid all complication and insure accuracy of results, I provide an upwardly-eX- tending connecting-piece or connector which supports directly or has formed upon it a horizontal guide-bar, which guide-bar moves bodily up and down in unison with the levers, while maintaining its parallelism with the horizon. Thus a connection may be established between it and the price or rate bar of the value-beam by means of a connecting piece or block adapted to move to any point along the guide-bar without affecting or varying the balance of the scales.

In the preferred construction a vertical bar or connector 12 is provided, on the upper end of which is directly mounted and supported IOO the horizontal guide formed by two bars 40 and 44, which bars, taken together, constitute a horizontal guide having a central slot, through which slot a pin or bottom piece 58 of the connecting-block 56 passes. The block 56 is supported on the guide-bar and is balanced up therewith, but is adapt-ed to form the connection between the barand the valuebeam, for which purpose it preferably has its upper end provided with an engaging portion which will take over the price-bar of the value-beam to cause said beam to oscillate in unison with the bodily up-and-down movements of the guide-bar.

The tare or weighing beam is pivotally connected with the vertical connector by means of bearings at ll, which as the weighingbeam is below the Value-beam are located intermediate the horizontal guide-bar and the platform-levers, and in this preferred construction the vertical connector is deflected or bent away from the pivots of the weighing-beam. Thus while the vertical connector may be brought in close to the beam-pivots these latter pivots andthe pivotal connection between the beam. and vertical connector will be somewhat widely separated.

The weighing or tare beam serves as a convenient means for balancing up or counterbalancing the platform levers, the vertical connector, horizontal guide-bar, and connecting-block, which parts, it will be understood, are put in perfect balance independent of the value-beam, and the latter is, as is usual in this class of scales, put in independent balance.

The beams are provided with sliding poises 8 and 51, which register with graduations indicating pounds and ounces and value, respectively, and in addition the beams have the usual pendants 9 and 52 atthe outerends.

An indicating-needle 53 is provided on the rear end of the value-beam, working ina beam-stop formed by the slotted head 54 on the bracket 55 and serves not only to indicate the balance, but also to limit the oscillation of the beams to the very small arc of movement necessary for them to have in the efficient working of the scale.

A platform or goods-receiver 13 is supported on the platform-levers by means of legs 36 37 or other usual provision made for receiving the goods.

In use the weight of the goods or tare may be ascertained by the use of the tare or weighing beam regardless of the position of the connecting-block, and when it is desired to indicate value the said con necting-block is shifted to register with the desired rateindication and bythe useof the Value-beam and poise 5l the scale putin balance, when the total value will be indicated by the graduation with which the poise registers. This pricing operation is of course reversed when an unknown quantity is to be given for a liXed sum. In other words, the scale is then first set and then the goods added to secure a balance.

Although I have in some respects specifically described the construction and relative arrangement of the several elements of my improved scale, yet I do not desire to be conlined to the same, as such changes and modifications may be made as fairly fall within the scope of my invention.
